A positive electrode and a negative electrode are stacked so as to face each other with a separator and a low spring constant film interposed therebetween. The positive electrode or the negative electrode has a first spring constant that is the lowest spring constant of the positive electrode, the negative electrode and the separator. The low spring constant film has a second spring constant. The second spring constant is lower than the first spring constant.
